Answer:
1/2
Step-by-step explanation:
Given that,
Height, p = 1
Hypotenuse, h = 2
Base = ![\sqrt3](https://tex.z-dn.net/?f=%5Csqrt3)
We need to find the value of cos60.
![\cos\theta=\dfrac{\text{Base}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Ccos%5Ctheta%3D%5Cdfrac%7B%5Ctext%7BBase%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
![\cos60=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Ccos60%3D%5Cdfrac%7B1%7D%7B2%7D)
Hence, the correct option is (e).
Answer:
a.) Time = 6 hours
b.) Average Speed = 410 miles per hours
c.) Distance = 196 miles
Step-by-step explanation:
<h3><u>a.</u>)</h3>
A coach drives 360 miles at a speed of 60 mph.
So,
Time = Distance ÷ Speed
Time = 360 ÷ 60
Time = 6 hours
<h3>
<u>b.</u>)</h3>
A plan flies 1640 miles in 4 hours.
So,
Average Speed = Distance ÷ Time
Average Speed = 1640 ÷ 4
Average Speed = 410 miles per hours
<h3>
<u>c.</u>)</h3>
A bus drives 3½ hour at an average Speed of 56 mph.
So,
3½ hour = 3.5 hour
Distance = Average Speed × Time
Distance = 56 × 3.5
Distance = 196 miles

The answer to the question
C. 4x +5y -34=0.thats the answer hope it helps
A.) P(defective | foo) = P(defective & foo)/P(foo)
4% = P(defective & foo)/30% . . . . . . . . . plug in the given data
0.04*0.30 = P(defective & foo) = 0.012 = 1.2%
The probability that a widget was produced at the foo factory and is defective is 1.2%.
b.) P(defective | foo) ≠ P(defective) (4% ≠ 5%), so the events P(defective) and P(foo) are NOT independent.
c.) P(foo | defective) = P(defective & foo)/P(defective)
P(foo | defective) = 1.2%/5% = 24%
The probability that a widget was produced at the foo factory given it is defective is 24%.
